Question

How do you solve `x^2=-9x-8`?

Answer 1

x= -1 or-8

Explanation:

First use null factor law to put the `-x^2` on the other side hence making 0= `-x^2` -9x-8. Simplify by dividing by-1 = `x^2` +9x+8=0. Then use cross method to factorise which becomes (x+8)(x+1)=0 the x being -8 or -1 as the answer
